Cable guidelines
ATTENTION!
Review and implement the following cable guidelines to
avoid signal interference or cable damage.
• Use RJ45 cable for the Network Management port.
• Use DB9 null modem cable for the console port.
• Confirm you have appropriate cables to attach the devices, for
example the server and targets.
• Do not bend fiber optic cables to a radius smaller than three (3)
inches. Doing so could result in serious degradation in
performance or complete loss of connectivity.
• Do not lay copper cables near transformers or alongside power
cables for any distance. Doing so could introduce noise into the
signaling.
• Avoid laying cables near sharp edges or where objects or other
equipment can crush them.
• Laser types at each end of any link must match.
